This would be best I think.  There's a related problem here.  Many  
operating systems (e.g. various Linux distros) provide system scripts  
written in Python and they incorrectly use /usr/bin/env.  The problem  
is that if you have your own version of Python earlier in your $PATH,  
you can break these scripts.  This happens when say your /usr/local/ 
bin/python doesn't have the packages that your /usr/bin/python  
expects.  I've hit this quite a few times on Gentoo for example.  In  
these cases, you really do want the #! line to point to the OS's  
version of Python rather than whatever random installation is on your  
$PATH.
